Doc changes for command line options

[Rik]

All,

I've trawled through the code and found a two shell environment
variables and a command line option that are undocumented.  As these are
undocumented, they are probably not being used or are only in use by a
few select installations.  I want to get the blessing of the maintainers
list to change the names on three of these before writing them up and
exposing them to the world in the manual.

--no-initial-path : Don't initialize the search path for function files
to include default locations.

I propose to rename to --no-init-path which would match the existing
option --no-init-file and seems just as clear.

Environment variable: OCTAVE_SITE_INITFILE which defaults to
$OCTAVE_PREFIX/share/octave/$version/m/startup/octaverc

Environment variable: OCTAVE_LOCAL_SITE_INITFILE which defaults to
$OCTAVE_PREFIX/share/octave/site/m/startup/octaverc

I propose to rename the second variable to OCTAVE_VERSION_INITFILE.  I
also propose to swap the two variables so that OCTAVE_SITE refers to
site/m/startup/octaverc and OCTAVE_VERSION refers to
$version/m/startup/octaverc.

Thoughts?
